“…}}$, and the other considers Si 4+ in the molten slag (see Supplementary C for more details). On the other hand, Xin et al [ 105,106 ] also developed an empirical model to predict the surface tension of the CaO–SiO 2 –MgO–Al 2 O 3 /Fe x O slag system by regression analyses of the experimental measurements. This model is described as

“…Indeed, Tanaka et al's model has been further detailed into two versions [104] : one considers the silicate structure SiO 4À 4 , and the other considers Si 4þ in the molten slag (see Supplementary C for more details).

Centrifugal granulation‐assisted thermal energy recovery (CGATER) remains the leading technology for the iron and steel industry to enable the low‐carbon treatment of high‐temperature blast furnace (BF) slag. Accurate knowledge of the thermophysical properties of BF slag is pivotal for the commercialization of the CGATER. However, it presents a formidable task to obtain these quantities due to the extremely high temperature of molten BF slag (≈1500 °C). To date, the thermophysical properties of BF slag have not been well characterized yet. Herein, five typical thermophysical properties including density, viscosity, surface tension, thermal conductivity, and emissivity are scrutinized with emphasis on the experimental measurements and empirical estimates. The working principles of these measurement methods are briefly overviewed and their merits and demerits are highlighted. It is noted that density, viscosity, and surface tension have been intensively studied; the quantities can be estimated with moderate uncertainty. However, the thermal conductivity and emissivity of BF slag are less tackled, mainly because of the scarcity of measurement tools at high temperatures. In the future, innovative measurement tools tailored for high‐temperature materials are essential, not only for enriching the thermophysical property database of BF slag but also for paving the way toward characterizing other complex high‐temperature melts.

“…CaO juga dapat memutuskan ikatan tetrahedral oksida pengotor pada konsentrat titanomagnetit. Hal ini akan menurunkan viskositas dan berat jenis terak sehingga memudahkan proses pemisahan lelehan logam dan terak pada proses peleburan di electric furnace [43]. Oleh karena itu, penambahan CaCO3 sebagai bahan imbuh lebih disarankan dalam reduksi konsentrat titanomagnetit dibandingkan senyawa kalsium lainnya.…”

Pasir besi atau titanomagnetit ditemukan di wilayah pesisir pantai Indonesia yang tersebar dari Aceh hingga pantai utara Papua. Kandungan logam berharga seperti besi, titanium, dan vanadium belum dimanfaatkan dengan baik karena hingga saat ini belum ada pabrik pengolahan dan pemurnian (smelter) di dalam negeri yang mampu mengolah pasir besi hingga menjadi produk akhir dengan nilai tambah yang tinggi. Perusahaan di dalam negeri hanya mampu mengolah pasir besi hingga menjadi konsentrat. Ulasan literatur ini disusun dengan harapan dapat menjadi salah satu langkah awal perkembangan teknologi pengolahan dan pemurnian pasir besi di Indonesia. Hasil ulasan literatur menunjukkan bahwa pasir besi atau titanomagnetit telah diproses baik menggunakan teknologi rotary kiln – electric furnace maupun tanur tiup (blast furnace). Penelitian terus berkembang ke arah teknologi reduksi langsung karena kemungkinannya untuk menghasilkan terak titanium dengan kadar tinggi. Artikel ini juga membandingkan parameter yang berpengaruh dalam proses reduksi langsung konsentrat pasir besi atau titanomagnetit yang terdiri dari pengaruh reaktor, reduktor, temperatur proses, dan penambahan bahan imbuh. Rekomendasi juga diberikan sebagai saran untuk perkembangan penelitian selanjutnya dalam reduksi konsentrat pasir besi atau titanomagnetit.

“…Vanadium-titanium magnetite (VTM), a type of complex iron ore containing iron, vanadium, titanium, is widely distributed in China, America, Russia, and South Africa. [1][2][3] Currently, vanadium-titanium magnetite sinter and pellet are conventionally used as the main feedstock of blast furnace (BF) smelting. However, due to the insufficient reducibility of VTM-sinter and VTM-pellet, the FeO content increased and the softening-melting temperature decreased obviously.…”
